Hello there,

I am trying to solve the problem of a flexible cylinder in a chanel flow. To solve the problem in 2D one must adjust the boundary conditions on every time step after solving the equations of motion of the cylinder (a mass with a spring). However one must also retain the velocity and position for the next time step. How can that be done with UDF? Can i have static variables?

Thanks

U can use User Defined Memory for storing those values.
